Description
Technical Field
The invention relates to an auxiliary heat preservation/sun shading system used in a sunlight greenhouse, and belongs to the technical field of sunlight greenhouse environment regulation. In particular to a dual-function environment regulating device which is arranged in a sunlight greenhouse and is used for improving the heat preservation performance and the shading capability of the greenhouse.
Background
The sunlight greenhouse is the most main facility form for vegetable production in spring, autumn and winter in northern areas of China, and the construction scale is still continuously expanded. From the structural characteristics, the sunlight greenhouse has better heat preservation and heat storage functions, and can realize the overwintering production in many areas under the condition of no heating. However, the following problems still remain: one is that the room temperature is low in winter. Although the sunlight greenhouse in many areas can basically maintain production in winter, the lowest temperature at night is usually at the physiological limit low temperature of plants, and the yield and the quality of vegetables are difficult to ensure; secondly, the utility model can not be used all the year round. At present, the sunlight greenhouse basically has no cooling regulation and control measures, so that the sunlight greenhouse is mostly in a fallow state in 6-8 months, and the annual utilization rate of the greenhouse is reduced.
The structural characteristics of the sunlight greenhouse determine that the part with the most heat loss is the light-transmitting surface of the roof, and accounts for more than 75 percent of the heat loss of the whole greenhouse. Although all the existing greenhouses are additionally provided with heat preservation covers on the outer surfaces of the light transmission surfaces, the factors such as price (economy), weight (influence on the structure) and the like need to be considered when selecting materials, the outer heat preservation covers of most greenhouses only have one layer, and even if the materials have good heat preservation performance, the heat preservation capacity is limited. In addition, the heat preservation quilt used for many years is often improper to store in summer, is easy to cause the phenomena of aging, damage and the like of the heat preservation quilt, further causes the problems of the heat preservation performance of the heat preservation quilt per se, the sealing performance of a lap joint and the like, and can seriously affect the temperature environment of the sunlight greenhouse at night in winter and even affect the production. Therefore, some people try to adopt an internal heat preservation system, but the adopted technical scheme is that a heat preservation quilt (curtain) does arc line or linear motion from top to bottom along a front roof, and gravity needs to be overcome when the system moves and stops, so that the operation traction force is large, and manual operation is inconvenient; most of the supporting systems are trusses or double-layer frameworks, and occupy the upper space of a part of greenhouse.
On the other hand, most sunlight greenhouses do not have sun-shading equipment, and only ventilation and cooling measures can be used for abandoning cultivation production when the solar radiation is too strong and cannot meet the regulation and control requirements. A few sunlight greenhouses with the sun-shading devices mostly adopt an external sun-shading mode, and although the sun-shading and high-temperature inhibiting effects are good, the input cost of the supporting system is high, so that the application in production is less.
